摘要
本文提出了一种单相AC-DC变换器，该变换器具有直流纹波补偿辅助电路和用于插电式混合动力汽车与电网双向潮流的DC-DC变换器。单相PWM电压源变换器直流母线上存在二阶谐波纹波电压。低频纹波电压通常使用直流母线上的大块电容器滤波，导致功率密度低且需要较大的空间。设计了直流纹波补偿辅助电路，减小了直流链路电容的尺寸。整体变流器配置，以双向潮流调节电网单位功率因数。在第一级，使用单相VSC将230 V 50 Hz的交流电源转换为400 V的直流电，并进行纹波补偿;在第二级，通过降压升压DC-DC转换器监控插电式插电式电池的充放电。降压模式用于充电，升压模式用于放电。在放电情况下，以230V, 50hz的电压回送电网。插电式混合动力使用的电池额定功率为1.8 kW，电压为120V。
Vehicle to grid and grid to vehicle bidirectional power flow at unity power factor with DC ripple compensation
In this paper, a single-phase AC-DC converter is proposed with an auxiliary circuit for DC ripple compensation and a DC-DC converter for bidirectional power flow between PHEV (Plug in Hybrid Electric Vehicle) and power grid. There is an existence of second-order harmonic ripple voltage on the DC bus of single phase PWM voltage source converter (VSC). The low frequency ripple voltages normally filtered using a bulk capacitor at the DC bus which results in low power density and require large space. An auxiliary circuit for DC ripple compensation reduces the size of DC link capacitor. The overall converter configuration, with bidirectional power flow regulates unity power factor at the grid. In first stage, a 230 V 50 Hz AC supply is converted in to 400 V DC with ripple compensation using a single-phase VSC and in the second stage, the charging and discharging of the PHEV battery is monitor through a buck boost DC-DC converter. Buck mode is used for charging and boost mode is used for discharging. In case of discharging, energy sent back to the grid at 230V, 50 Hz. A battery rating of 1.8 kW at 120V is used in PHEV.
